SUBMARINE BOAT.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed February 3, 1914. Serial No. 816,225.

To all whom it may concern:

Be it known that I, HANS TECHEL, a citizen of the German Empire, residing at Kiel, Germany, have invented certain new and useful Improvements in Submarine Boats,

.of which the following is a specification.

owing to the short path of descent traversed when they slide off, have only a comparatively low velocity imparted to them, and therefore when sliding off the said mines may easily strike against the hull of the boat or, if they are already in the water, and sliding along the struck by the screw.

The object of the present invention therefore is to provide a submarine craft of the kind hereinbefore mentioned, in which the mines can be so brought into the water, that all danger of injurious contact of the said mines with any part of the craft is avoided.

A constructional example of the subject matter of the invention is illustrated in the drawing in which- Figure 1 is a vertical longitudinal section of'a submarine boat constructed according to the invention. Fig. 2 is the'plan view corresponding to Fig. 1 and Fig. 3 is a sectlon on the line 33 of Fig. 1 looking from the left, while Figs. 4 and 5 show details on a larger scale.

5A is the thin-walled outer hull and B the ,ressure proof inner hull of the submarine cat. The mines C are so arranged that they can be thrown out over the stern of the boat. For this purpose they are arranged to travel in two longitudinal rows in channels D in I the non-water tight platform of the boat.

The wheels of the underframe E of each mine, which is at the same time constructed to act as a mine anchor, run in U-shaped guide rails F. r

The traveling mines are transferred and ejected by endless chains K being arranged in pairs for each hull of the boat, may be chains J and K, the latter' row of mines. The chains are passed over rollers L M and N 0 respectively and can be driven by a motor S mounted in the interior of the boat. The chains J and K are driven at different speeds, so that the longer or transferring chains J are driven slowly and the shorter or ejecting chains K rapidly. This is accomplished in the present case by making one and the same shaft Q, drive the chains J through a worm wheel gearing R and the chains K through a bevel wheel gearing P.

At fixed intervals, determined by the length of the mines, the pivot bolts of the chains J and K are extended on both sides and in this way fashioned into tappet bolts 2' and la, into the path of which latter forkshaped stops G and H on the under frame of the mine project (see particularly Figs. 4 and 5). Clutches U and V (see Fig. 2) which can be thrown into and out of operation from the interior of the boat, enable one set of chains (the one on the port side in the present case) to be stopped. In order to compensate the weight of the boat and the trimming moment, which change with the throwing out of the mines, two ballast tanks W W are employed of which the former is arranged amidships and the other in the rear part of the ship.

' direction of the arrow at (see Fig. 1) toward the stern of the boat. When the first mine carriage has advanced so far that its front wheels are located over the chains K, the tappets k on these chains engage with the stops H on the mine carriage and in consequence of the greater; peripheral velocity of the chains K, impart to the mine When commencing to such a speed that it is thrown outward clear of the stern of the boat, without striking against the latter.

From the foregoing, it will be seen that the invention embodies a slow conveyor for transferrin the mines from a receiving point to a elivery point whlch is near the "21m, and u fast c-Qnveyer which mass from the trmmfesring eoniu point dehwr emri imam mounted upon' carriage are 1 1 L0 travel #1 e YQRS ts the point at, which ivex'i by the transferring con prov-21 1 ,m mini; done the. and may run special davice for L 10k"; is providafi. the and :1 11* W121i 2 12. way, u i Va, and he inink"). tanks ii: so i .aemiateiy mforaa mine N152; flai-i.
